I tried using Pyrodex years ago but found that it tended to soak up oil worse than real black powder did, besides I have always been a bit of a purest, like the real stuff, now having said that I was introduced to Alliant's substitute black as an alternative to the real stuff in my cartridge loading. I was very surprised at how well it did and how much easier it was to clean up after. The main reason though was it was locally available at a very decent price where as no one within 100 miles of me sells the real stuff. There are a lot of reasons why people buy and use what they do and I have tried to never judge the choices of others, what do I know about their situations? If a person is willing to get into the muzzle loading sport, or black powder cartridge game, because of the availability or convenience of fake black powder more power to him, at least his presence in the overall game helps to support the availability of related products. I am old enough to have seen a great deal of change in this sport over the years and watched the loss of many fine products, and the introduction of a lot of stuff I really don't like, such as inline black powder firearms. When those became popular several traditional black powder firearms went the way of the Dodo bird and that was a very sad day, but like them or not they help keep the sport alive, and honestly we all need that. Hang in there folks, and have a great day, after all it's the Christmas season, one of the best times of the year....well, at least in my book.
